2011 Volvo S80 Fuel Economy

Across the board, the S80's powertrains are very thirsty, and this is one of the S80's chief failings—though Volvo has dropped the thirstiest, the V-8, for 2011. The base six-cylinder version gets 19 mpg city, 27 highway, and even the turbo T6 version, with all-wheel drive, only gets one mile per gallon lower.

However in drives of the S80 we've seen numbers toward the lower end of that scale in mixed driving—mostly because of this sedan's 4,000-pound-plus heft, we suspect.

The 2011 Volvo S80 isn't anything close to a guzzler, but as an everyday commuting vehicle it's not very green.
